Unformatted text preview: (a) Determine the characteristic impedance Z o . (Assuming w >> d, and fields are confined in between the two plates) (b) If the transmission line is operating at 1 GHz, and the transmission line is of length 75 mm, determine the input impedance of the transmission line if it is shorted at the far end ( z = 75mm). L = 75 mm plates w d z = 0 z = 75 mm...
